When your leaves start to lose their colour, your landscape might be asking for help.
If leaves start to fade from rich green to pale yellow, it’s easy to assume it’s just part of their cycle. But in many cases, that colour change can be a sign of leaf chlorosis, which is a condition that signals your plants aren’t getting what they need to thrive.

Leaf chlorosis happens when plants are unable to produce enough chlorophyll, the pigment responsible for their green colour and overall vitality. The cause is often rooted below the surface. Common triggers include compacted soils, poor drainage, high soil pH, and nutrient imbalances such as a lack of available iron or manganese.
Certain trees and shrubs are particularly prone to leaf chlorosis in Collingwood, Ontario. Maples, oaks, birch, and some ornamental species can struggle when planted in soils that don’t match their needs. You may notice leaves turning yellow between the veins while the veins themselves stay green, along with reduced growth and thinning canopies over time.
Managing leaf chlorosis starts with understanding why it is happening, and quick fixes rarely solve the problem long-term. That’s where our approach at WillowStone stands out. We look at the full picture of your landscape, combining soil testing, plant health assessments, and site conditions to identify the root cause of a problem.
